To all whom it may concern.'

Beit known that I, WILLIAM F. THOMPSON, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain' new and Improved Duplex Conductor for Use in Combination with VireRod Mills; and I do hereby declare that the following is a full, clear, and complete description thereof.

The nature of my invention relates to an improved dualistic system of conductors or guides used in connection with wire-rod mills, to facilitate not only the operation of rolling wire rods, but also largely increasing the capacity of the mill and causing less waste of stock than in the ordinary operations.

That the improvement may be more fully seen and understood by those skilled in this art, reference will be had to the annexed specication and the accompanying drawings, of which- Figure l, Plate l, is an elevation view of a pair of coupled three-high rolls provided with a dual guiding or conducting mechanism from one set of rolls to another. Fig. 2 represents A a horizontal section of the rolls on line xx and a plan viewr of the main part of the conducting apparatus in connection with the rolls. Fig. 3, Plate 2, is a vertical section in line x a', Fig. l. Fig. et is also a vertical section on liney y. Enlarged Fig. 5 is a face view of a detached section of said mechanism. Enlarged Fig. 6 is an end view of one of the conducting-pipes with its Haring mouth, detached from the mill mechanism or appliances.

Like letters of reference refer to like parts in the several views.

In the drawings, A and A represent a pair of mills of three-high rolls arranged in line with a train of other mills, (not shown in the drawings,) adapted for the rolling and reduction of wire rods. On one or both ends of this train of mills is arranged a set of three-hi gh pinions, (not shown,) which receive motion from any suitable motor, and are mounted in housings of the same construction as those used in connection with the rolls. The spindies B of the rolls C C are provided with a fluted extension, a, (technically known as warblers,77 and seen in Figs. l and 2,) over which the thimbles D are fitted to transmit motion from one mill to another and primary rotation from the said pinions to the first mill.

Of these mills or threelhigh rolls only two rolls are grooved for the gradual reduction of wire rods. lThe third roll is a dummy or blank one, which alternately runs either on top or bottom of the respective grooved rolls, for a purpose as hereinafter shown. These mills in pairs are arranged to co-operate one with another by means of a duplex conducting mechanism, as seen in Figs. l and 2, which consists of a duplex semicircular grooved conductor, E, and the guide-pipes F, G, and H. On one side of every mill-housing a groove, l', is formed, in which the slotted bar J is adjusted and held in the required position for the purpose of supporting the guideholders K and L, Figs. 3 and 4. By means of the slot within the bar J said holders can readily be shifted in a horizontal direction without removing the bolt M to adjust the guide-pipes in line with the respective grooves of the rolls. The pipes F guide the wire rods (after passing through the rolls of the mill A) either into the outer or inner channel, d d, of the conductorE above referred to, and for that purpose they are made tapering and closely held up (see Fig. 3) to the bite of said rolls, that the wire rods may Vrnove freely and easily enter the pipes, b-ut leading the same through an opening much smaller than the entrance. By this means the tendency is to discharge the wire in a straight course into the conductor E, Figs. 2 and 3. The pipes F are securely connected within and by the guide-holder K by means ofa setscrew, c, as seen in Figs. l and 3, and in the enlarged Fig. which illustrates a face view of the same.

In Fig. 5 it can readily be seen that the cover K is constructed to lit over the lugs b, attached to the lower part of said holder K, and that by means of the set-screw c a fixed connection ofthe pipe F, the guide-holder K, and cover K is had. In this way no extra means for the smaller end of the pipes F are required to hold the saine within the grooves or channels d d of the conductor E, as Seen in Figs. 2 and 3.

The conductor proper begins at the point where the bifurcated channels d d unite into a duplex conductor at F.

This conductor E is supported The inner sides of roo by two or more standards, N N, as seen in Figs. l and 3. The lower part of said standards is secured to the iioor, and the upper part to the base of the conductor, a slot, n', in one or both parts, and having screw-bolts, which arrangements allow of a vertical variation to adj ust and hold the conductor in such position as the rolls may determine. In Fig. 1 only a part of the base of said standards is shown, so as not to hide other parts from view.

As aforesaid, the conductor in part is a duplex semicircle, which at the terminus E' bifurcates into the guides e e, to serve as means for the attachment of thc pipes G G, and to direct the rod in line to the flaring mouths G G thereof. The lower sides of the flaring mouths G G' of the pipes G G are provided with a slotted hole, as seen at f', Fig. 2, for lateral adjustment in connecting the pipes with the conductor. rIhe pipes H H, as well asthe pipes G G, consist of halvesj and Z m, divided longitudinally, as seen in Figs. 3, 4, and 6. The halvesA are hinged together at g, and provided with a spring-latch,

g', and lug h, as seen in Figs. 2 and 6. rlhe pipes G and H are made in sections,`for the reasonl that the pipe H will wear out at the end toward the rolls much sooner than the rest of the pipe; hence the cost of replacing the pipe H is much less than the cost would be for the whole length from the conductor E to the liners O O of the guide-holders L L.

To provide for the opening ofthe pipes G and H by means of the lids, as before stated, is an essential feature of this invention, in so far as a ready admission to the interior of these pipes may be obtained in case of accident-such as the breaking or bending of the rods in the passage through-the conductor and guide-pipes-for the removal of such obstructions. The rods are fed in between the grooved rolls C C of the mill A, as seen in Figs. 2 and 3, and their course when leadingsaid rolls is directed by the guidepipes F F and the channeled semicireular conductor E, in which the wire rods while yet in a heated state are bent to follow the line of said conductor to and through the pipes G H and the guide-liners O O, wherein the rods are properly introduced for reduction between the rolls ofthe mill A. The flaring mouths of the pipes G afford an easy and accommodating communication with the conductor E, which is especially essential as soon as the rods are stretched or forced over the conductor into the bifurcated guides e e when the train of rolls are active, as the iiaring mouths tend to receive and direct a diverging rod in line to the pipes.

The guide-holders L L are attached to the bar J in like manner as the holder K. The pipes H rest on the plain front part of these holders or supporters and extend in between the daring guide-liners O, which are secured in place by the set-screws h'.

In Fig. l the conductor E is shown as connected with the upper and lower pair of rolls of the mills A and A', which is necessary in order to lead the rods between rolls turning in opposite direction to each other, that the wire can enter and leave'the rolls, as indicated in Figs. 3 and 4. The blank roll C is only used in cooperation for the transmission of power from one roll to another in a proper direction.

By the means heretofore in use the feeding or entering of a new rod had to be delayed until the entire length of the preceding rod was taken through the reducing-rolls, thus greatly impairing the efficiency and capacity of the mills.

By the construction and arrangement of the improved mechanism herein described no delay need occur in waiting with the feeding of one rod until the other has completely been drawn through by the reducing-rolls, for the reason that the pipes and channels of this dupleX conductor will lead two rods simultaneously from the grooves of the mill A, thereby greatly increasing the capacity of the rolls or mill.

If a rod on passing through the pipes G and H becomes bent, broken, or twisted, thereby forming an obstruction within said pipes, the lid of the respective pipeis then readily opened and the obstruction removed, while the rod in the adjoining groove or pipe can be drawn along between the rolls independent of the interruption in the other circuit.

This improvement reduces the liability of the said rods bending or breaking in the transit from the rolls A to the rolls A', as the conductor and guide-pipes C H with the `flaring mouths cause a safe guidance of the rods from one set of rolls to the other, as before stated; hence there is less waste of stock and an increased capacity and a higher percentage of results than by the ordinary means.'

The described mechanism of the conductor and attachments, in connection with the rolls, may be so enlarged and arranged as to lead and conduct more than two rods simultaneously from one set of rolls to the following reducing-rolls in essentially the same way as the transit of two rods from the rolls A to and through the rolls A', before set forth.

What I claim as my invention, and desire to secure by Letters Patent, is
